摘要： PROBLEM TO BE SOLVED: To provide a gas meter which assures precision of a cross section area of a path of a flow channel to be measured in which a fluid flows, and precision of a flow rate of the fluid measured by an ultrasonic flow measuring means, with reduced cost.
SOLUTION: In the gas meter, a pair of ultrasonic transmit-receive means are located to face each other in a flow channel to be measured. The flow channel to be measured comprises a body case, and a straight measuring tube for flow rate measurement stored in the body case. The measuring tube is connected using two L-shape members (52a and 52b) whose cross section in the vertical direction against the flow direction is L-shaped so as to make the cross section of the tube is rectangular. At the position where the ultrasonic transmit-receive means is located, an opening (52c) is provided. In addition, a turbulent flow suppression member (54) which has micropore to pass through ultrasonic waves is provided at the opening. The measuring tube also comprises a member whose coefficient of linear expansion is not greater than a prescribed value.

摘要： PROBLEM TO BE SOLVED: To distinguish whether excessive flow rate is actually being generated in the fluid of an object of measurement or failure is generated in a flow rate sensor, such as a ultrasonic wave propagation time measuring part or a flow rate value operating means, such as a flow rate value arithmetic circuit system. SOLUTION: When the signal or the operation result of flow rate corresponding to excessive flow rate is detected, an abnormality discriminating control circuit 40 closes a cut-off valve 94, even to a prescribed opening, and performs operation which reduces the effective conduction cross section of gas flow. Before and after the reduction, the signal output from an ultrasonic wave propagation time measuring part 20 or a flow rate value, computed by the flow rate value operating part 30, is detected. On the basis of progress of the detected signal or the flow rate value, it is discriminated whether a failure is generated in the measuring part 20 or in the operating part 30, or excessive flow rate is actually generated in gas.

摘要： PROBLEM TO BE SOLVED: To improve combustion of a burner combustor by using a NOX sensor. SOLUTION: A NOX sensor 23 is provided on the exhaust side of the burner combustor. A memory 19 stores data on reference concentration of NOX for carrying out a combustion improvement. During a combustion operation, a comparing part 21 makes comparison between a NOX concentration detected by the sensor 23 and the reference concentration stored in the memory 19. When the detected concentration is higher than the reference concentration, a command for raising air flow rate is issued to a fan rotation controller 22, which, on receiving the command, controls the rotation of a combustion fan 5 in the direction for raising the air-flow rate. An air flow insufficiency caused by stopping up of exhaust is eliminated, and NOX generation is restrained to attain a clean combustion of less NOX emission.

摘要： PURPOSE:To perform bathtub wash perfectly and suppress wasteful use of water by spouting the washing water from a nozzle into a bathtub, dropping contaminants with chemical action and the spout energy of water, and finally flushing away the washing water with a clean water. CONSTITUTION:A nozzle 6 rotating with water pressure is mounted at the center of the inner surface of a lid 5, and when bathing is finished and the lid 5 is set correctly, the service water is spouted from the nozzle 6 to bring away the dirt, etc. Detergent solution is injected into a buffer 2 from a vessel 8, and No.1 three-way valve 19 is changed over to the heating device side. Heating is maintained, and the washing water is spouted from the nozzle 6 into the bathtub 1 to perform washing. Then, circulation is made by a circulating pump 16 following the route as the nozzle 6, bathtub 1, buffer 2, a circulation hole 2' for returning, (heating device 11), circulating pump 16, No.1 three- way valve 19, No.2 three-way valve 19', and again the nozzle 6. Thus, the insides of the bathtub 1, buffer 2, and circuit of circuilating pump 16 are filled with the detergent solution, followed by flushing away with clean water.
